Transfer speed (up to) 150MB/s. The SanDisk Ultra Flair USB 3.0 Flash Drive features a stylish yet tough metal casing that protects the drive from unexpected knocks.

EDIT: Thank you to who added the Non-Prime price.

These seem great at first but after owning two of them my experience is that they only seem to run at advertised speed for a few seconds at the start, then quickly drop down to USB 2.0 levels for the rest of the operation, I feel as though they've designed it to do a burst of speed at the start so they can say they are fast for marketing purposes but the drive can't seem to maintain that speed no matter the type of files you copy, they also get extremely hot to the touch, to the point of concern...

That's just my experience, who knows maybe they can keep the advertised speed up for longer but I haven't seen it happen yet after formatting one a few times to keep an updated Windows installer on it.

Edit: Good price for an actual memory stick regardless though so hot, I just believe you won't get the speed advertised for longer than a few seconds...

Have a couple of them but they dont work in loads of USB3.0 ports which can be a real pain.

That's exactly my experience as well... Would not buy again.

It'll be fine for that. I've used 8-16Gb USB2 ones that are almost certainly slower than this & they've been ok.

Other customer reviews on Amazon confirm the same. The drop in speed is either due to thermal throttling (I don't know if cheap controllers for usb sticks bother with this though), or a TLC flash memory with just a bit of SLC cache.
In addition to the low transfer speeds, these USB's have a well known design fault and get horrendously hot when in use - almost to the point where it's uncomfortable to hold them in your hand.
